It is metal, so it get hot when you put it into the soy wax. Be careful and use pliers to hold it. With this grill I stamped the whole fabric.
In both today's as well as the previous blogpost I used snow, but this could also have been done using ice dubes. As you have seen, soy wax works great in combination with snow and ice dyeing, but keep in mind that not all resist will work that well. Resists which dissolve in water like potato dextrin, sugar, baby food do not work. While the snow or ice melts, it dissolves the resist. You will get some pattern on your fabric, but not as clear defined as you might have wanted.
